` TYPE-WRITING MACHINE.

Specification of Letters Patent.`

Patented Apr. 26, 1910. Divided and thisk application filed Juliek 8`1909. Serial No. 500,885.

To all whom. it may concern:

Be it known that I, Fnnnnnicii ALEXAN- DER, a citizen of the UnitedStates, residing at New York city, borough of Brooklyn, county of Kings,State of New York, have invented certain new and useful Improvements inType-lVI-iting Machines, of which the following is a clear, full, andexact description.

. The object of this invention is to provide a combined paper clip andmarginal stop for typewriting machines, whereby the paper clip isshifted every time a marginal stop is moved to regulate the extent ofthe writing on a sheet of paper. By shifting the paper cli with themarginal stop the paper is kept in contact with the platen more firmlythan if the paper is held against the platen at opposite ends.

Other advantages and details of improvenient will hereinafter appear,and the novel features of my invention will be pointed out in theclaims, rference bein had to the accompanying drawing, forming parthereof, wherein- Figure 1- is a cross-sectional view ofl a typt-.writingmachine frame and carriage slidably mounted thereupon, a part of saidview being in elevation; Fig. 2 is a top plan view of the carriage and aportion of the frontl rail of the frame; Fig. 3 is a front end viewof-the carriage; and Fig. 4 is van enlarged sectional top plan view ofthe marginal stop and latch carried thereby, the -section being taken ona line a-a in Fig. V3.

Referring to the drawing, the numeral 1 indicates a frame upon which acarriage 1a is slidably mounted, said lcarria e carrying a. platen 2around which t e paper passes. The end members of the carriage l" areconnected, at the front thereof, by a bar 3, which is provided with anelongated opening 3". The lower rail 3b is rovided with rack teeth 4,and the top rai with a marginal scale 5: to slidably support a marginalstop combined with a paper clip, which I Will now describe.

My improved marginal stop and paper clip comprises a block 6 which has(in thisA instance) integral therewith a bracket. 7. The bracket 7slidably supports a plate 8,

which is provided with an elongated slot TheI front bar 3 is designed' lgu, through which a binding screw t) passes in order to secure the plate8 in an adjusted position. The plate 8 vcarries a paper clip 10, whichis pivotally secured to the said plate, as at 11. A spring 12, carriedbythe clipk 10,. exerts a slight pressure and serves to keep the clip incontact with-the paper on the platen 2. lVhen tlievstop or block- 6 clip10 ofi' the paper; hence the pivotal connection 11. As can be seen inFig. l, the block G, has, also, in this instance, integral therewith abox-frame 12a which is adapted to embrace the front bar 3, whereby theblock (3 and paper clip are snugly but slidably connected to the saidbar 3.

In order to lock the stop 6 and paper-clip l() in an adiustcdvpositionalong the rack 4, I provide the stop G with a latch 13, having anextension 13"', which isadapted to engage the teeth of the rack 4, theextension 13 being provided with an elongated slot 13a through which amachine screw 14 can pass and engage the block G (see Fig. 4).- A.spring l5 of suificient pressure serves to hold the latch 13 in anengaged or open position., To stop the carria e at any desired point, Iprovide a movable pin 17 having an upstaiiding end 18 adapted toimpiiigc the stop G. The pin 17 is provided vwith a head 19, a spring 20serving to hold the pin in an operative position.

Should I desire to cause the carriage to travel but a short distance, Ipull out the latches 13 until the extensions 13b leave the rack-teeth. Ithen move the entire stops and clips aloii the bar 3 and lock them bymeans of the atches 13 and rack 4 in the desired position, indicated bythe scale 5. lVhen the carriage moves during the opera- -tion ofwriting, the extension 18 on the pin 17 will contact the stop 6 on theright in Fig. 2 when the desired extent of travel has beenmade. Vhen thecarriage is returned for a new line, the stop on the left of Fig. 2 willContact the extension 18 of the pin 17. Should I. desire to remove thecarriage, the pins 17 can be pulled outwardly against the tension of thespring 20-and held out until either of the stops 6 has passed it. pin 17is preferably positioned at about the .center of the front rail .17

The stop 6 aiidpapcr clips may be positioiied at any point along therack 4.

I aving now described my invention, what I claimand desire to secure byLetters Patent is:

1. In a. typewriting machine, a carriage provided with a platen, a rackadjacent sald platen, marginal stops slidably mounted adacent said rack,releasable means carried y said stops adapted to engage said rack andlock said stops against Amovement, a

each of said sto s, a late carried by each of said brackets a apt forlongitudinal adjustment thereupon, and a paper clip pivotally mounted on4each of said plates adapted to contact with said platen.

2. In a t eiwritin machine, a carria e YE g g platen, marginal stopsslidably mounted adjacentl said rack, a releasable latch carried bysaidstops ada ted to engage `said rack and lock said) stops a inst movement,a bracket' carried by'each o said stops, a plate carried by each of saidbrackets adapted for longitudinal adjustment thereu on, a paper chppivotally mounted on eacli of said plates adapted to contact with saidplaten, and a spring carried b each of sald lates adapted `to kee thecllips carried thereby in contact wi ate. y p Signed at 'New York city,N.
